For nearly all computer users, losing data can be a very traumatic experience. If you use your computer for a business or for other important matters, it can be very stressful and very traumatic to lose everything you have worked months, and possibly even years to build. Even though you may back up your data on a periodic basis, you will still need to check the backup to make sure that everything works. Nothing can be worse than backing something up, only to find months later that something went wrong.
